Given numbers are 979,678,788,890
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 979,678,788,890 is 1307611140.
Find LCM of 979,678,788,890 with Prime Factorization
| 2 | 979, 678, 788, 890 |
| 89 | 979, 339, 394, 445 |
| 11, 339, 394, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 89 x 11 x 339 x 394 x 5 = 1307611140
Therefore, the lowest common multiple of 979,678,788,890 is 1307611140.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
979 x 678 x 788 x 890 = 465509565840
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
979 : 1, 11, 89, 979
678 : 1, 2, 3, 6, 113, 226, 339, 678
788 : 1, 2, 4, 197, 394, 788
890 : 1, 2, 5, 10, 89, 178, 445, 890
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,678,788,890, is 1.
Now, the common factors can be found like this.
979:11x 89
678:2x 3x 113
788:2x 2x 197
890:2x 5x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 89 = 356
Therefore, the value for common factors is 356.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 465509565840/(1x356)
LCM = 465509565840/356
LCM = 1307611140
Thus, we can understand that the LCM of 979,678,788,890 is 1307611140.
